Was doing the step in accordance with what they had planned. Already knew that in the initial phase would lose some time in overtaking insofar as there were enough dust and didn't want to run any kind of risk. But then I started having more open terrain and able to walk further. However, the half a dozen kilometers from the arrival, I realised that I was low on petrol and was forced to determine progress, not to run the risk of getting stopped in the middle of the selective sector.
